Abstract.

The 111Ru nucleus, populated in the spontaneous fission of 248Cm has been studied by means of prompt gamma spectroscopy using the EUROGAM2 array. Spin and parity assignments, based on angular correlations, linear polarization, and conversion coefficient measurements differ from those available in the literature. New bands are reported, which incorporate γ transitions seen previously but not placed in the scheme of 111Ru or placed incorrectly. The bands are interpreted as neutron excitations into subshells originating predominantly from the h11/2, g7/2 and s1/2 spherical orbitals. The s1/2 band, strongly mixed with the d3/2, d5/2 and g7/2 configurations, is observed for the first time in this region.
